CTA coverage also decreases when parking at shallow angles (refer to
figure for approximate zone coverage areas [sensor obstructed to
vehicle on left]
).

CTA detection limitations: Due to the nature of radar technology,
there may be certain instances where vehicles entering and exiting the
blind spot zones may not be detected. Below is a list of circumstances
that may cause non detection:
• Debris build-up on the rear quarter panel fascias
• The rear quarter panel radar beams are obstructed or partially

obstructed by an adjacently parked vehicle or object.

• Approaching vehicles passing at speeds greater than 15 mph

(24 km/h)

• Severe weather conditions
• Driving in reverse faster than 3 mph (5 km/h)
• Backing out of an angled parking spot
CTA False Alerts

Due to the nature of radar technology, there may be certain instances
when the BLIS

௡ will alert with no object present when backing up. This

is known as a false alert. Some level of false alerts are normal.
Circumstances that may cause a false alert when backing up are backing
out of a garage, backing in to a parking space, and objects very close to
the sensor. False alerts are temporary and self-correct.
